It is a glace satchel but the mid size (which is the only one I liked) was only made for department stores. The Prada stores had a size smaller and a size larger. It also came in the pinkish to grey patent. I don't know more than that, sorry! It sold out pretty fast, that I know.
I had a ball at the Prada sale yesterday -- went absolutely nuts as the whole runway collection was 1/2 off but no handbags so posted in the wardrobe thread: http://forum.purseblog.com/the-wardrobe/prada-1-2-price-sale-excursion-214003.html
